OUTPUT (mV)
The F9892-21/-22 are ideal detectors with large effective
area for TOF-MS (Time of Flight Mass Spectrometry).
Our own advanced technology in optimizing the assembly design with flat MCP allows excellent time resolution
of 0.9 ns Typ. (FWHM) with negligible ringing at both
±10 kV high voltage floating operation.
